Methods for delaying aging of polymer cable trays
Edit:Shan Dongfang Kai Polymer Materials Co., Ltd.   PublicDate:2019-09-03

    With the wide application of cable trays, there will be failures in use, such as polymer cable trays In the aging phenomenon, the polymer cable tray is mainly insulated by the outer layer of sheath. If the protection is not good, the insulation performance will gradually decrease, and the aging will become hard, brittle or fall off, thus failing to function as insulation. The following describes the method for delaying aging of polymer cable trays.
    I. Regular inspection of polymer cable trays
    See if the overall structure of the polymer cable tray is stable. In actual use, cable trays are often loose or deformed due to various external factors, which can affect the cable. At this time, routine inspection can detect hair treatment early, avoid problems in the power transmission link, and threaten the safety of people and objects around.
    2. Check the working environment of the polymer cable tray and the parts of the joint and fixed parts.
    Due to weather and other factors, the components of the polymer cable tray may be damaged or corroded, so special attention should be paid to the inspection here.
    3. Remove dust or other debris from the surface of the polymer cable tray. Keep the polymer cable tray clean and ensure the environment around the cable tray is clean. Neat to protect the bridge from corrosion and tidy appearance.
    The polymer cable tray and the external environment and heat source around the cable will also cause the temperature of the polymer cable tray to be too high, the insulation breakdown, and the cable aging phenomenon, if it is serious, it will also cause The explosion caught fire. Therefore, we must pay attention to the timely polymer cable tray, and the environment used.
